Keep encountering "Error 56" when starting the VPN client

Hello all. I recently downloaded the VPN client to connect to my school's Unix servers. The first time I downloaded it, it worked just fine. But now for some reason, the service will not start at all. When I go to start>programs>Cisco Systems>VPN client, it seems to load, but after about a minute, I get this error message: "Error 56: The Cisco Systems, Inc., VPN client has not been started. Please start this service and try again." I've tried going to the Cisco folder and clicking on the .exe files, but they don't seem to do anything. Clicking on "cvpnd.exe" and "vpnclient.exe" don't bring up anything, and nothing appears in the task manager.

Keep encountering "Error 56" when starting the VPN client

I just had this same issue with the client on Windows 7. I initially tried the previous post but windows would not let me stop the service. A reinstall and removal of the virtual adaptors then reinstall got me back on. Thanks David!
